“…Such a complex excitation spectrum, containing 15 different laser frequencies, can be produced by direct, external, or combined modulation of a laser diode [45][46][47]. We note, however, that the spin polarization can also be achieved by driving the system with only four excitation frequencies at any one time: Once a pair of hyperfine states has been depleted, one pair of driving frequencies can be shifted to the next step in the polarization ladder, since the leakage by decay across two nuclear states is expected to be negligible.…”

Transition metal (TM) defects in silicon carbide (SiC) are a promising platform for applications in quantum technology. Some TM defects, e.g. vanadium, emit in one of the telecom bands, but the large ground state hyperfine manifold poses a problem for applications which require pure quantum states. We develop a driven, dissipative protocol to polarize the nuclear spin, based on a rigorous theoretical model of the defect. We further show that nuclear-spin polarization enables the use of well-known methods for initialization and long-time coherent storage of quantum states. The proposed nuclear-spin preparation protocol thus marks the first step towards an all-optically controlled integrated platform for quantum technology with TM defects in SiC.

“…The downstream link is realized with a continuous optical source emitting at 1344nm followed by a Mach-Zehnder Modulator (MZM) where a NRZ 50Gbit/s modulation is applied by a PPG with PRBS length of 2 31 -1. For lower cost purposes, this emitter type could be replaced by a DFB with and Electro-Absorption Modulator (EAM) as demonstrated in our previous work [9] . However, no DFB-EAM emitting at 1342+/-2nm was available for these experiments.…”
